I applied online and received an email from their recruitment. Got scheduled a series of calls, and then received a home task assignment. After delivering my solution proposal to it, got scheduled a call with an engineer from the company to review it. Things were looking good and I was advancing round after round. Right before the last interview in the process, which is a conversation with their CEO, I got rejected with some poor explanation for the reasons. They told me I was good, but they had some better candidates. At the same time they kept posting the same role and new ones. I liked the company, but it seems that they are not completely sure what they are looking for. What was funny is that one of their engineers shared that the company had hired into an engineering role a pilot, who had lost their job due to Covid. I felt terribly, as I have been building my engineering expertise for more than a decade, this is also what my BSc degree is in, and to be outperformed by a pilot!? This is some very weird company :)

first stage hiring manager interview, It is a 4 stage process, interview was conducted online via teams, next stage would have been engineering manager interview, then technical then final interview.
